In chemical combination of H-atom with sodium. It gains an electron but in case of HF, H atom.
Correct answer: B. Loses 1 e
- A. Gains 2 e
- B. Loses 1 e
- C. Loses 2 e
- D. Gains 2e
Explanation
.Option B is correct since, in the case of HF, fluorine is more electronegative than hydrogen, so it gains one electron to complete its octet while hydrogen loses one electron to become stable.Option A is incorrect since hydrogen does not gain 2 electrons to form HF.Option C is incorrect since hydrogen does not lose 2 electrons to form HF, it loses one .Option D is incorrect since hydrogen does not gain 2 electrons to form HF.

About Chemical Bonding
Chemical bonding explains molecular shape through VSEPR theory and distinguishes sigma bonds from pi bonds. Questions involve hybridization, bond angles, dipole moment and bond energy, including how electron-pair repulsion determines geometry and how bond polarity differs from the overall polarity of a molecule.
